Associations between inflammatory markers in endobronchial mucosal biopsies and bronchial wash. Spearman’s rank correlations. A p-value < 0.05 was considered significant (N = 14). A Association between endothelial P-selectin expression and epithelial neutrophil numbers in endobronchial mucosal biopsies after BD100 exhaust exposure (r = 0.74, p = 0.003). B Association between neutrophil numbers in the bronchial submucosa and bronchial wash (BW) after BD100 exhaust exposure (r = 0.560, p = 0.037)
